We’re at that point in January when resolution starts to waver. The siren call of the cream bun is deafening – that of the gym barely audible. And because dry January is one of the hardest resolutions of all, we thought it a good moment to bring you some motivation – a reminder of why a month of sobriety is worth the effort.

If you keep going, experts say, by the end of January, you will most likely be sleeping better – and who doesn’t want better sleep? You’re also likely to have increased energy and spare cash in your pocket.

And if the January blues are leading you to look into holidays for the year ahead, you could try ‘regenerative travel’ as a way to avoid contributing to over-tourism. The idea is to give back to the communities you visit while you enjoy a break, such as by staying in a locally-run guesthouse or farm. Something worth investigating in 2025.
